The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]

The Ryzen 7 1800X is AMD's flagship Ryzen CPU. Clocked at 3.6 GHz with a turbo frequency of 4.0 GHz (stock) this chip offers a staggering level of multi-core performance. Comparing the 1800X with the Intel i7-6850K shows that the 1800X delivers 25% more multi-core throughput than its more expensive counterpart. Historically AMD's CPU architecture has had a much lower IPC than Intel's and consequently Intel have dominated the CPU market since 2009. Comparing IPC between Intel's Kaby Lake and Ryzen shows a maximum gap of just 9%. A very welcome shake-up of the CPU market will unfold as the remaining Ryzen 5 and Ryzen 3 models are rolled out. For now the 1800X offers workstation users similar processing power to a $1,000 i7-6900K at half the price. [Mar '17 CPUPro]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
